Description

Technical Field

[0001] This utility model belongs to the technical field of laser gas sensor equipment, specifically referring to a batch aging and calibration device for laser gas sensors. Background Technology

[0002] Laser gas sensors are widely used in environmental monitoring, industrial safety, and medical diagnostics due to their advantages such as high sensitivity, high selectivity, and fast response.

[0003] The laser gas sensor uses the Coordinated Semiconductor Laser Absorption Spectroscopy (TDLAS) technique to detect the concentration of the gas being measured. TDLAS technology has matured over many years and has advantages such as high sensitivity, the ability to detect a wide variety of gases, and real-time online monitoring.

[0004] However, existing batch aging and calibration devices for laser gas sensors are all manually operated, which is cumbersome and complicated. This results in low calibration and testing efficiency for laser methane sensors, and the problems of cumbersome operation, low efficiency and difficulty in ensuring consistency are not addressed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model proposes a batch aging and calibration device for laser gas sensors. This device effectively solves the problems that the batch aging and calibration of laser gas sensors is all manually operated, which is cumbersome and complicated, resulting in low calibration and testing efficiency of laser methane sensors, and is cumbersome, inefficient and difficult to ensure consistency.

[0006] The technical solution adopted by this utility model is as follows: This utility model proposes a batch aging calibration device for laser gas sensors, including a base, a detection structure on the base, and a precision calibration structure located above the detection structure. The precision calibration structure works in conjunction with the detection structure to perform aging measurements.

[0007] Preferably, the detection structure includes a multi-channel power supply base fixedly mounted on a base, a calibration light installed on the multi-channel power supply base for calibrating the aging laser gas sensor, an aging data display screen installed on the multi-channel power supply base for testing the aging degree of the laser gas sensor, a sensor mounting base fixedly mounted on one side of the base, a sensor fixing bracket installed on the sensor mounting base, and the sensor mounting base electrically connected to the multi-channel power supply base via a sensor wire.

[0008] To achieve better testing results, the accuracy calibration structure includes hydraulic lifting columns fixed on both sides of the base. A fixed base is fixed above the hydraulic lifting columns, and a gas mixing chamber is fixed below the fixed base. High-transparency glass is installed at the bottom of the gas mixing chamber, forming a cavity inside. A standard gas cylinder is fixed above the gas mixing chamber for filling with test gas. The standard gas cylinder is connected to the gas mixing chamber through an air pump inlet pipe and an exhaust pipe. The standard gas cylinder is also connected to the gas mixing chamber through an air pump outlet pipe. A gas measuring gauge is installed on the side wall of the gas mixing chamber.

[0009] To achieve the detection objective more quickly, both the multi-channel power supply socket and the sensor mounting base are equipped with internal circuit modules.

[0010] Furthermore, the calibration light and aging data display screen are connected to the laser gas sensor in the sensor mounting bracket via a sensor wire, thereby realizing aging test and calibration.

[0011] To achieve accurate detection, the standard gas cylinder is filled with test gas, which is circulated into the gas mixing chamber by gas pump one and gas pump two, and the reference data is calibrated by a gas measuring instrument.

[0012] The beneficial effects of this utility model using the above structure are as follows: The proposed laser gas sensor batch aging calibration device has a multi-sensor fixing bracket on the sensor mounting base, which can simultaneously install multiple sets of laser gas sensors, thereby realizing multi-group synchronous detection. The aging degree of the laser gas sensors is displayed on the aging data display screen, and light marking is performed by calibration lights, achieving high testing efficiency.

The precision calibration structure 3 cooperates with the detection structure 2 to perform aging measurement.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the detection structure 2 includes a multi-channel power supply base 4 fixedly mounted on the base 1. A calibration light 5 is installed on the multi-channel power supply base 4 for calibrating the aging laser gas sensor. An aging data display screen 6 is installed on the multi-channel power supply base 4 for testing the aging degree of the laser gas sensor. A sensor mounting base 7 is fixedly mounted on one side of the base 1. A circuit module is installed inside the multi-channel power supply base 4. A circuit module is installed inside the sensor mounting base 7. A sensor fixing bracket 8 is installed on the sensor mounting base 7. The sensor mounting base 7 is electrically connected to the multi-channel power supply base 4 through a sensor wire 9. The calibration light 5 and the aging data display screen 6 are connected to the laser gas sensor in the sensor fixing bracket 8 through the sensor wire 9, thereby realizing aging test and calibration.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the accuracy calibration structure 3 includes hydraulic lifting columns 10 fixedly mounted on both sides of the base 1. A fixed seat 11 is fixedly mounted above the hydraulic lifting columns 10, and a gas mixing chamber 12 is fixedly mounted below the fixed seat 11. A high-transparency glass 13 is installed at the bottom of the gas mixing chamber 12, forming a cavity inside the gas mixing chamber 12. A standard gas cylinder 14 is fixedly mounted above the gas mixing chamber 12 for filling with test gas. The standard gas cylinder 14 is connected to the gas mixing chamber 12 through the inlet and outlet pipes of air pump 15 and air pump 26.

[0023] In practical use, first, control the hydraulic lifting column 10 to push the gas mixing chamber 12 on the fixed base 11 to rise from the sensor mounting base 7. Then, install the laser gas sensor into the sensor fixing bracket 8 on the sensor mounting base 7. Next, control the hydraulic lifting column 10 to lower the gas mixing chamber 12 on the fixed base 11 above the laser gas sensor. At this time, the laser gas sensor is attached to the high-transparency glass 13 below the gas mixing chamber 12. Then, control the air pump 15 to fill the gas mixing chamber 12 with the detection gas through the standard gas cylinder 14. At this time, the gas measuring gauge 17 measures the gas in the gas mixing chamber 12 as the reference data. Then, control the laser gas sensor in the sensor fixing bracket 8 on the sensor mounting base 7 to measure the gas in the gas mixing chamber 12. At the same time, the data is transmitted to the aging data display screen 6 through the sensor line 9 to display the aging degree and compare it with the data on the gas measuring gauge 17. Then, the aged laser gas sensor is marked by pressing the calibration light 5, thereby efficiently completing the calibration and testing.
